The results show that the addition of surfactant shortens induction time and improves formation rate and volumetric proportion, and the volumetric proportion of synthetic hydrate samples can amount to 136~150; the existence of porous medium delays hydrate formation exiguously; the influence of memory effect on gas hydrate formation is notable, the induction time could be shortened by 10~20 times for the experimental system containing residual pentahedral ring structure.

结果表明：表面活性剂的加入缩短了水合物生成诱导时间，提高了生成速度和含气率，合成的水合物样品含气率达到136~150；多孔介质的存在对水合物的生成有较小的延缓；记忆效应对瓦斯水合物生成影响显著，在拥有水合物分解残余五面体环等结构的实验体系中，水合物生成诱导时间缩短10~20倍。

The solubization power of two surfactants was much stronger than that of three cyclodextrins, which was determined by their different solubilization mechanisms.

两种表面活性剂的增溶能力比三种环糊精的强，这是由这两类物质不同的增溶作用机理决定的。

The fourth chapter investigated disperse of attapulgite in organic medium, such as sdimethyl-benzene and carbinal, in aqueous solution with different pH, different surface-active agent, firstly.
